In a previous paper we reported observations on the blood sugar values during fasting in normal new-born infants.1 In this paper we report the results of studies on the dextrose, saccharose, lactose and dextrimaltose tolerance in new-born infants. In addition, the blood sugar curve after a breast feeding was determined in eighteen infants. We found a number of reports2 in the literature on carbohydrate tolerance in infants ranging in age from 1 month to 2 years, but a careful search failed to reveal any studies on new-born infants.
In all the work done, the values of the blood sugar were estimated on blood from the great toe, according to the technic described in a previous paper.1Three hours after a feeding, the blood was taken and the sugar content was determined. Immediately after the blood was taken, 2 Gm. of dextrose, saccharose, lactose or dextrimaltose per
